i had sleeping problem for months too, it haunted me for years and keep coming back.
due to hectic work schedule and insane ot.

unless it's really serious, do not take sleep pills. bed is for sleeping, if you cant sleep, wake up to read book, watch tv ect.
dont roll on bed, dont use smart phone, light up your room with weak ambient lighting, download rain sound/brown noise generator app, listen the rain sound will help you fall a sleep.
passive noise blocking earphone will help too.
my ears are sensitive to sound, so i wear earplug almost everyday before sleep, for almost a decades already lol.
